Back to brewing after a long summer off and I failed to remember we only have one 2L flask to build a starter. I'm wondering if there's a chance I could just make one big, stepped starter (built based on yeastcalc.com) and pitch that into an 11 gallon batch of 1.059 stout split into two carboys or if making one big starter in such a small flask would stress the yeast too much. How would you all approach this?
1.5-2L stepped starter too small for two vials??

If it was me, I'd go with a two steps. First being ~1.7L to get you close to 300 billion cells, crash in fridge for a couple days, pour off the wort on top, then a ~1.3L starter and pitch the yeast slurry from the bottom of the first step to get you up to the 500+ billion cells you need. That will get you what you need.
Hard to say without knowing your starting cell count.
Can you give this info?

This is pretty much what I was thinking but just wasn't sure.
The starting cell count will be ~156Billion.

From Mrmalty.com, yeast starter faq:
It sounds to me like your second step may be too concentrated to produce a significant increase in healthy cell count. I would just go to Walmart and buy a cheap gallon container. There is a thread about a rubbermaid container with a flat bottom at Target(?) for cheap that works great on stir plates, if you're using one.

I would do 1 vial in 1 liter, then decant and add 1.75 liters and the other vial then pitch the whole thing after 2 days on the stir plate.
